目的探讨与分析航天员常压下着舱内航天服时的热生理指标变化规律。方法６ 名健康男性青年按二次复合设计分组共进行２４ 人次试验，对结果进行统计分析。结果经分析计算获得了人体主要热生理指标随通风气源参数（ 风温、风量、风湿） 及人体活动水平的数学模型，对模型的应用及可能影响试验结果的代谢产热等因素进行了定量分析讨论。结论 模型反映了人着航天服时的热生理变化规律。
Objective To explore and analyze the changing rules of the thermophysiological indices of astronauts under atmospheric pressure with space suit. Methods Six healthy male youths were divided into two groups according to the second compound design to conduct a total of 24 person-time trials, and the results were statistically analyzed. Results The main thermophysiological parameters of human body were obtained with the mathematical model of ventilated air source parameters (air temperature, air volume, rheumatism) and human activity level. The application of the model and the metabolic heat production which may affect the test results were quantified Analysis and discussion. Conclusion The model reflects the thermal physiological changes when people are wearing space suits.
